bitching and moaning that she had the flu,an ingrown toenail,chest pains – and,,furthermore,better things to do than play “Survivor ” – Morasca emerged victorious over the other contestants,earning a $1 million prize and outwitting,outlasting and out-playing the men by winning all the challenges.

Perhaps it was a ploy.But whatever it was,we decided to give the 23-year-old Pittsburgh native our own challenge:

Find a sexy,stylish outfit with only $100.

“It ‘s going to be tough,” she admits.. Has winning the $1 million made her less budget-conscious than before?

“There are times where I will splurge,” she says.”I couldn ‘t buy it before,but I can now.Still,it ends up being expensive.”

Morasca – who describes her style as edgy,stylish and comfortable – is in town to promote her newest venture,”Model Challenge USA,” a national competition wherein female contestants vie to win modeling contracts and photo shoots.

Along for the buying spree is her boyfriend, Ethan Zohn,who won “Survivor:Africa.”

When she shows up to go shopping,Morasca looks fabulous in Joe jeans,a Victoria ‘s Secret coat, gold Botkier bag and a scarf that Zohn ‘s mom made her. She ‘s looking for an outfit to wear for “Model Challenge USA.” We begin the day at Armani Exchange in SoHo.

Let ‘s see if she can win this challenge.

Armani Exchange 568 Broadway;(212)431-6000

Everything in this store is arranged neatly by color and style (men ‘s on the left,women ‘s on the left).Morasca pulls an adorable sweater with sequined hearts from the racks.”I love it,” she says.”Look Ethan,it has hearts on it.” “But

is it on sale?” asks Zohn,,reminding his girl-friend that she ‘s only got $100.It ‘s $58.He ‘s right.

She realizes it ‘s time to hit the sales racks in the back. Luckily there are lots of cute tank tops and sweaters on sale for under $70.Morasca pulls a low-cut pink top that ‘s only $39.99.”Ethan,do you like this?” she asks..”It ‘s pretty.” “Is it one of those [sweaters ] that shows cleavage??” he asks,while raising his eyebrows.Morasca laughs.

“A little cleavage never hurt anyone,” she says.”And I ‘ll look pretty in pink.” We ‘re off to find the rest of the outfit at Blue-fly.store,a new outlet shop on Wooster Street.

Bluefly.store

102 Wooster St.;(917)687-9673

This massive store is like a designer dream house for all those who can ‘t afford Barneys Co-op next door.Endless racks of overstocked items from the fashion Web site Bluefly.com are for sale – from Nicole Miller dresses for

$50 – to Ralph Lauren sweaters for $$39.99.

The store is temporary,though,so shoppers need to get their digs in,pronto.”You have to have time to go through everything because if you rush,you ‘re going to miss some good stuff,” says Morasca..

The price of the dress?A mere $50. Lastly,it ‘s time to get some shoes.Loads of designer shoes – from Dolce &&Gabbana heels to Christian Louboutin strap sandals – line the back of the store.But the only pair of shoes that are somewhat decent (and reasonably priced)are a pair of Marc Jacobs gold satin pumps.Even though one shoe was missing a sequin clasp,at $37.50,Morasca can ‘t resist.It ‘s not like anyone will notice.

The outfit looks great.”I like the dress because it ‘s girly and something I wouldn ‘t normally pick out for myself,” she says..”I would definitely wear the dress out.The gold shoes are great.They didn ‘t look that good on the rack,but once I put them on,they look really cool.”
